My main interest is in Andrew Adams (born 1781 Md). William Sr is not his father (I have his will). Andrew Adams married Catherine Marker, Peter is presumably a close relation (brother?) The Teeter, Marker, Albaugh & Adams families all appear in present Carroll Co, Maryland (then Frederick) in the Taneytown to Silver Run area. In Frederick Co, two of Valentine (s/o Martin) Adam's children married children of William (Wilhelm) Albaugh. In the 1800 census of the Taneytown District of Frederick Co, one of the Zachariah Albaugh is two lines from Thomas Adams (John, Martin). Lease map of Monocacy manor in Frederick Co shows Zachariah Albaugh (Sr?), lots 60-62, adjacent to Andrew Adams, lot 29 (originally to Martin Adam, willed 1754 to his son Andrew).
So, there's a lot of Adams/Albaugh connections. Wherever I look for my Andrew Adams (Frederick Co, Bedford Co, Cambria Co) I find Albaugh in the same district of township. I'm hoping this can help me figure out who my Andrew Adams' father is.
